Changing the Loop Frequency:
HY-5B detectors can never crosstalk. If for any reason, you want to manually change the loop frequency, change
the Installer Menu option for the desired loop from 0 to 3, and then press the Select button. Each detector
has a choice of four frequencies. Press the Select button when the desired frequency setting is found, and the
controller will perform a reset and tune to the new frequency setting.
Call Strength Level:
Knowing the call strength of a detector is valuable because it provides information about how well the loop is
actually “seeing” a specic vehicle. For example, it may be useful to check to see if the loop is easily detecting
the middle of a high bed semi-truck. The strength of a detector call can be displayed in real time, on a scale of
0 to 7. As indicated in the table below, when the Installer Menu setting for a given detector is set to 2, and the
Menu button is pressed, the LCD display will read Level 0 - 7 Call Level. If the call strength on the display appears
as a level 4 or less, consider increasing the sensitivity level by adjusting the rotary switch on the HY-5B detector.
